This hub is dedicated to addressing challenges affecting Cameroon’s arid and semi-arid regions (Adamawa, North & Far North), particularly those related to climate change, environmental vulnerability, nutrition, agriculture, and food security. Research initiatives focus on climate resilience, sustainable agricultural systems, drought adaptation strategies, nutritional health, water resource management, and community-based interventions that strengthen resilience among vulnerable populations. The hub seeks to generate evidence-based solutions capable of improving livelihoods, reducing food insecurity, and supporting sustainable environmental management.
